Converting the other way: square kilometers to square meters

square meters = square kilometers × 1,000,000. So 0.000001 square kilometers is back to 1 square meter; one square kilometer is 1,000,000 square meters. See the square kilometers to square meters table.

Quick estimate in your head

For a rough answer, multiply by about 0.000001: 1 × 0.000001 ≈ 0.000001 km2, against the exact 0.000001 km2 (0.0% out). Good enough to check that a calculated result is sensible.

Common mistakes

The usual slip is using the factor the wrong way round. A square meter is smaller than a square kilometer, so the number of square kilometers must come out smaller than the number of square meters. If your answer goes the other way, divide instead of multiplying.
